CAR-COUPLING.

Specification of Letters Patent.

Patented Sept. 17, 1918..

Application filed April 2, 1918. l,Serial No. 2265213.

To all whom 'it may concern:

Be it known that I, RoBnRTvKEYs AnnensoN, a citizen ofthe United States, residing at Blountville, in the county of Sullivan and State of Tennessee, have invented new and useful Improvements in Car-Couplings, of which the following is a speciication'.

This invention relates to car couplings and it consists in the novel features hereinafter described and claimed. 0

An object of the invention is to provlde a car couplingV of simple and durable structure the same having means whereby two couplings may be automatically joined or connected with each other.y and means adapted to be readily operated for permitting the coupling members to disengage from each other. Y v

With this object in view the coupling comprises a head provided at its side portions with vertically disposed slots or guides. A shaft is journaled in the guides and cai'- ries atits ends disks which are concentrically positioned thereon. A second shaft is jcurnaled at a xed point in the lower portion of the head and at the lower ends of the slots and carries at its ends diskswhich are eccentrically positioned thereon and upon which the first mentioned disks rest. A crank handle isrprovided upon the second mentioned shaft. The coupling link is provided at its upper side and in the vicinity of its ends, which are pointed, with recesses one of which is adapted to receive the upper shaft in the coupling head.

In the accompanying drawings Figure l is a longitudinal sectional view of one of the coupling members.

' Fig. 2 is a side view.

Fig. 3 is a longitudinal section with 'the parts in uncoupled position.

Fig. 4 is a section on the line 4 4 of Fig. 1.

The coupling comprises a head 1 which is provided with the usual throat 2 adapted to receive the end portion ofa link 3. The

link 3 is pointed at its opposite ends and the Vsaid link is provided at its Vupper side and in the vicinity of its ends with transversely disposed notches 4.

The head l is provided at the opposite sides fof the throat 2 with vertically disposed guide slots 5 and a shaft 6 is loosely received in the said slots. The shaft 6 carries at its ends circular Y disks 7 which are concentrically positioned upon the said shaft. A shaft 8 is journaled in the head l below the guide slots 5 and circular disks 9y are eccentrically positioned upon the shaft 5. The disks 7 `rest upon the disks 9.- A crank handle 10 is fixed to one end of the shaft 8. Y

The disks 9 are of such weight that their centers of gravity will normallyflie below the axis of the shaft 8. Inasmuch as the disks 7 rest upon the disks 9 the axisof the shaft 6 is normally in a relatively close position to the shaft S. When the end ofthe link 3 is inserted between the shafts 6 and 8 the pointed end portion of the said link will lift the shaft 6 and the said shaft may-turn Aand roll along the upper side of the link 3 until it enters the approaching notch, 4, when the shaft 6 will drop into the said notch. Thus the link 3 is connected with the coupling head. To uncouple the link from the head the shaft'8 is turned by using the handle 10 whereby the disks 9 are turned y and the deep parts of the eccentric lof which the disks 9 are component parts will move above the axis of the shaft 8 and therefore the disks 7 and the shaft 6 arelifted and the shaft 6 is carried above the upper edges readily withdrawn from the coupling head.

From the foregoing description taken in conjunction with the accompanying drawings it will be seen that acar coupling of simple and durable structure is provided and that the same may be easily and quickly manipulated to effect the coupling and uncoupling of two coupling members.

Having described the invention what is claimed is:

A coupling comprising a head provided with a throat and having at its sides vertically disposed guide slots, a shaft loosely mounted in the guide slots, Vcircular disks mounted upon the shaft and concentrically positioned with rela-tion thereto', a shaft journaled in the lower portion of the head and below the ends ofthe slots, and circular disks mounted upon the last mentioned shaft and eccentrically positioned thereon, the first mentioned disks resting upon the peripheries of the last mentioned disks.l

In testimony whereof I aliix my signature.
